v MEANS FOR CASTING'METAL.

To all whom it may concern:

Be it known that I, lV LLIAM HENRY VVIL' LIAMS, subject of the King ofGreat Britain, and residing at BlOnIfOiCl Lane, Erdington, Birmingham,England, have invented certain new andusefullmprovements in Means forCasting Metal, of which the following is a specification. v I

This invention'comp'rises improvements in and relating to the methodsandmeans of casting metals, in which the metal is melted in a crucibleor pot placedin a furnace and. subsequently conveyed out of the furnacefor pouring-the metal into ingot or strip molds or into any other moldsused in casting operations. The invention is distinct from tiltingfurnaces in which metal is melted and poured out bodily tilting thefurnace- In accordance with my invention I provide a receptacle orcradle to receivea pot or crucible'for molten metal the receptacle orframe'comprising a tilting device whereby the pot or crucible may bebodily tilted pivoting about a point which is about the posi tion of thespout or nose of the pot. The receptacle is preferably on Wheels orrunners and may travel on a track to the molds and in the case of strip,or ingot, or tube molds the latter may conveniently be arranged in arackalongside which the receptacle carrying the pot may travel.

In the rack or stand the molds can be placed so as to be all at the sameangle and in correct position for receiving the poured metal as the potis tilted by its cradle intopouring position. The cradle may be tiltedby a lever or other mechanical power multiplying device so that thetilting of the pot presents little or no difficulty and as by theposition of the rack and the carriage track the relation between the potand the mold is correctly established, no spilling of metal is likely tooccur and the pouring operation is rendered easy and safe.

. Fig. 5 is a perspective view of the cradle and fork of the tiltinglever in the position seen at Fig. 1.

In this example of my invention I have shown the cradle mounted on atraveling carriage or. running frame on a track a alongside a rack orframe 6 which has a cl one near the upper part of the frame and one nearthe lower part, and on each ofthese studs (Z a yoke bar 0 may bearranged adapted to pass across say two molds and behind each yoke baris a handle nut f for applying pressure. By this means the two halves ofeach mold may be more rapidly clamped together than by the rings andwedges now commonly used, as two molds may be dealt with simultaneously,and further the molds may thereby be secured in the rack b. The moldspreferably have a receiving lip or mouth 9 on one side directed towardthe rack and communicating with the interior of the mold.

The traveling carriage may comprise any suitable frame provideolwithrunners for traveling on the track a aforesaid and has two upstandingsides or brackets h providing bearings, or a fulcrum, for a forked leverj. Beyond the bearings the lever y' continues down and the extremitiesof its fork 70 receive and engage the squared or other appropriateprojections Z of a cradle 92?. in which the pot a of metal is received.The cradle m may comprise for example one or more rings 0 for encirclingthe pot and a central cranked bottom bar 79 on which the pot may rest.

The axle g on which the forked lever is mounted in the sides or bracketsit may be curved at the part r between the bearings to pass around thefront of the pot a just below the spout to form a rest. or support whenthe pot is tilted.

As the lever j is swung down its fork extremities 7i: are raised andraise the cradle m in which the pot a is placed, thus tilting the potinto pouring position, see Fig. 4-.

metal or alloy, means for raising and tilting said cradle, said meanscomprising a forked lever with the fork ends connected to the cradle,and a stand portion providing a fulcrum for said lever adjacent to theportion occupied by the spout of the crucible when in said cradle.

2. For casting metals and alloys the combination of a cradle for acrucible of molten metal or alloy, means for raising and tilting saidcradle, said means comprising a forked lever with the fork endsconnected to the cradle, and a stand portion providing a fulcrum forsaid lever adjacent to the position occupied by the spout of thecrucible when in said cradle, said stand comprising a base part withupstanding brackets which'provide the fulcrum for the lever.

3. For casting metals and alloys, the combination of a cradle for acrucible of molten metal or alloy, means for raising and tilting saidcradle, said means comprising a forked lever with the fork endsconnected to the cradle, and a stand portion providing a fulcrum forsaid lever adjacent to the position occupied by the spout of thecrucible when in said cradle, said stand portion being provided with acarriage or running frame.

l. For casting metals and alloys the combination of a cradle for acrucible of molten metal or alloy, means for raising and tilting saidcradle, said means comprising a forked lever With the fork end'sconnected to the cradle, and a stand portion providing a fulcrmn forsaid lever adjacent to the position occupied by the spout of thecrucible when in said cradle, said stand comprising a base part withupstanding brackets which provide the fulcrum for the lever, and saidbase Copies of this patent may be obtained for part being rovided with acarriage or running frame.

5. For casting metals and alloys, the combination of a cradle to receivea crucible of molten metal or alloy, means for raising and tilting saidcradle and said crucible, said means comprising a forked lever. with thefork ends connected to the cradle, and a stand portion providing afulcrum for said lever adjacent to the position occupied by the spout ofthe crucible when in said cradle, a rack for supporting molds with atrack adjacent thereto, and a carriage on said track on which carriagesaid stand portion is mounted so that said crucible in said cradle maybe tilted by said lever to pour metal into any mold in said rack.

6. For casting metals and alloys, the combination of a cradle for acrucible of molten metal or alloy, means for raising and tilting saidcradle, said means comprising a forked lever with the fork endsconnected to the cradle, and a stand portion providing a fulcrum forsaid lever adjacent to the position occupied by the spout of thecrucible when in said cradle, said stand comprising a base portion withupstanding brackets which provide the fulcrum for the lever, and saidbase portion being provided with a carriage or running frame, a rack forsupporting molds with a track adjacent thereto on which said carriagemay travel, said rack having means for clamping said molds in inclinedposition therein so that said crucible in said cradle may be tilted topour metal into any mold in said rack.

In testimony whereof I afiix my signature.
